Title: Someone wants to build some additional 3D Objects for me? :> It's easy!
Post by: annikk.exe on June 10, 2011, 08:00:49 PM
If you guys could spare a bit of time, some assistance with this will really help me, as it will let me try stacking objects together and test the re-usability of the engine.


How to:

Full Template:
(click to show/hide)

The full template is currently set up to draw a simple cube.  You can change the function's name "DrawCube" to something else if appropriate... "DrawSpacecraft" would be excellent ^_^


Any questions, please ask!  If you make a cool 3D object, please post it and I'll go test it to see what it looks like.  :>

Here's another example of a simple pyramid design:

Even basic objects like squares and rectangles would be super-useful...  :>

Ok, but maybe you can give us the code to visualize it?

Ok sure, attached.  :>  Once your objects are complete, you can paste the entire function into this level file and call the function in the appropriate place.  Then you'll be able to see the object you designed.  :>
The cube and pyramid functions are already in there.

If anyone is not sure how to put their own object design into the level, just post your design here and I will sort it for you.  :>

Is there any way to tweak the poisitions at runtime in the console?

Post by: Pilchard123 on June 10, 2011, 08:58:54 PM
Aino, use DrawSprite(int id, x,y, r,g,b,a, size) With these as the the IDs. You'd probably want 5, 6 or 7, though they wouldn't interact with the 3D stuff.

0            Point,
1            Spot,
2            Wing,
3            Background,
4            Noise,
5            CircleFill,
6            Ring,
7            ThickRing,
8            Atmosphere,
9            UIWindow,
10            UIButton,
11            UIButtonPressed,
12            UIButtonHighlight,
13            Pixel,

And the edges ofcourse, but I meant a sphere :)

Edges join 2 vertices together.  :>
Alternatively, you can think of edges as lines that are drawn between one star and another star.


A circle would be very difficult to make as you can only use straight lines.  So you'd need a ton of vertices arranged in a roughly circular fashion, then you'd need an edge to connect each one to its neighbours.

Uhhm, I understood that fine, but the double bracket is confusing me :S
Title: Re: Someone wants to build some additional 3D Objects for me? :> It's easy!
Post by: Pilchard123 on June 10, 2011, 09:13:23 PM
There is a way to rotate a point around an arbitrary axis, so you could use that to get the coordinates or the new points from a planar circle. (which you got from doing the same, just with a point.) Edges, though? They'd require a bit of work to do. No, they wouldn't.

Post by: annikk.exe on June 10, 2011, 09:15:39 PM
The double bracket means it's a matrix.

Don't worry, it's pretty simple; the first bracket should always have "i" in it.  The second bracket should contain the edge ID for that vertice; simple ascending numbers like 0, 1, 2, 3, 4, 5, 6, etc.

Code: [Select]
edge[i][0] =
edge[i][1] =
edge[i][2] =
edge[i][3] =
edge[i][4] =

And annikk, add an "ultimate" size, which determines the size of the drawing, cause if you want two of the same things, but at different size, you must rewrite the whole thing :/

Edit: unless it's already there, but I didn't see it :P
Title: Re: Someone wants to build some additional 3D Objects for me? :> It's easy!
Post by: Aino on June 10, 2011, 09:17:07 PM
So the first number is where it sends from and the last is where it send the line to?

Edit: Realised it, I'm stupid :S

Explanation: The first is the vertex and the last is the number for that vertex, like the 4th edge for the first vertex :)

Is there any way to reefer to the WHOLE of an array/matrix? Say I had the array

x = {0,1,2,3,4,5,6,7,8,9}

Can refer to the whole thing at once?
Title: Re: Someone wants to build some additional 3D Objects for me? :> It's easy!
Post by: annikk.exe on June 10, 2011, 09:22:43 PM
it's edge[ID of the vertex we are drawing FROM][ID number of the edge] = ID of the vertex we are drawing TO

Not quite sure what you mean... yes, with a "For" loop.


Also someone mentioned an attribute that governs the overall size of an object.  I will implement this later, and it will be simple to convert objects over to the new system.

For now, all objects have a relative size of "1".  Later you will be able to change this, for example you would be able to change the modifier to 2, and that would result in an object double the original size.  Changing the modifier to 0.5 would result in an object half the original size, and so on.
That's not implemented yet, but as I say, it will be simple to do so when the time comes.

Regarding rotation of objects,

I have written code to do this.  However, I have not included it in this version of the engine, for some reason.

If I'm testing, do I have to have edges? Or does the system survive without any edges set?

Yeah, matrices are a pretty advanced subject.  They aren't too hard to explain (think of a spreadsheet basically), but thinking of a simple demonstration of their use can be quite hard.  That kind of puts me off covering them in a guide... though I will eventually, I guess.  :>

But if you want an infinite nuber, yours reaches 1000, which is a decently number...

Back to infite... as you for example explore more, how do you increase the matrix number?

The 1000 is the number of edges that can be created.  I don't think we'll be seeing 1000+ edged objects for a while yet.  It would be very costly on the CPU apart from anything else...

Awww...I was working on a sphere and my comp crashed (bluescreens, I hate 'em). Then I had to go and revise for my maths exams. Than Aino got there first. Poo.

...

Now I'm gonna prefab Aino's sphere and make a bunch of semi-primitives.

Awesome!! :D


Sorry to hear about your crash though.  That must have been annoying. :/

Is there any way of making more than one object? So, like:


A box over here



                                                                                                                                             And then another down here?



And have them both work as you would expect of two independent objects?

Yep!  Just call DrawCube (or whatever) twice, with different coordinates in the argument.  :>

EG:

Code: [Select]
DrawCube(200,200,200)
DrawCube(-500,-500,500)

Oh, okay. Can you bind two objects together - such as creating a cube with a sphere growing out of its corner - and have the two behave as a single object?
Title: Re: Someone wants to build some additional 3D Objects for me? :> It's easy!
Post by: Aino on June 10, 2011, 11:50:43 PM
In my experience with this, it would require some coding :P

Post by: Pilchard123 on June 10, 2011, 11:53:18 PM
Oh, okay. I think I have have idea how to do this actually.
Title: Re: Someone wants to build some additional 3D Objects for me? :> It's easy!
Post by: annikk.exe on June 11, 2011, 12:14:14 AM
Yes, that would be possible.  There are two methods you could use to do this:

1) When moving/rotating objects, you refer to all the vertices over both objects at the same time for all your transforms.

2) (This option is better for transportability) You can combine the two object functions into a single object function.

Yeah, I'm working on a function to combine two objects, also on improving the wireframe engine you posted earlier (making it so you don't have to have loads of code in the level file)

Is there any way to create an object outside of StarfieldInit? Like in ScreenDraw, or LevelDraw?
Title: Re: Someone wants to build some additional 3D Objects for me? :> It's easy!
Post by: annikk.exe on June 11, 2011, 03:50:48 AM
Not sure.. you could try calling the DrawCube() function from ScreenDraw() and see what happens I guess...  I think it will probably break though as it's not designed to do that currently.

Post by: Pilchard123 on June 11, 2011, 03:54:18 AM
I never actually said why I did this, did I? Basically, I've edited the 3D Engine slightly to make the actual level file less messy.


Oh. Well, I'll just have to release what I have done, then. Is it ever likely to be edited to allow ScreenDraw and LevelDraw? For now, shapes have to be created still in StarfieldInit().

Your Resources/Maps folder should look something like this for every map that uses this variation of the 3D engine.

Maps
--Stuff
--Map using 3D Engine, based on Tidy Engine (e.g. AMap) The filepaths in this map should be something like C:\\Program Files\\steam\\steamapps\\common\\eufloria\\Resources\\Maps\\AMap\\3DEngine\\Engine.lua
--AMap (Folder)
--------3DEngine
------------Engine.lua
------------Shapes.lua (only if this is being used)
--More stuff

Is there any way to reefer to the WHOLE of an array/matrix? Say I had the array

x = {0,1,2,3,4,5,6,7,8,9}

Can refer to the whole thing at once?

Yes, there is. If one was to use just the name of the array/matrix, in this case x, that will refer to the whole thing. Funny, I'm sure I tried that.

Also, may I enquire as to what the point of CaveMech is?

Now working on an editable sphere. I think I know how I'm going to go about it, but now I've got to learn how to use the engine.

Might do the same for cubes and pyramids, too.

Why have it split into so many files/folders?  Isn't it more convenient for players that download the maps if they only have to handle a single file?
Title: Re: Someone wants to build some additional 3D Objects for me? :> It's easy!
Post by: Pilchard123 on June 11, 2011, 06:49:12 AM
Hm. Yeah, but it's not so messy for those that want to have a look at the code, and easier on the eyes at design time, too. Just thought I'd see what people thaought.

It also makes it more customisable - you can add custom shapes more neatly.

I've managed to get shapes drawn in ScreenDraw, but it draws them every frame, and overlays the new on the old. This crashes, quickly.

If there any way to add vertices in a for loop (using a different iteration varioable than i, obviously). I don't seem to be able to...

EDIT: After more experimentation, it seems that all the vertices bar the first are not drawn unless they have edges to/from them. Intended, or not?

New method of adding edges.
I've converted the Cube over to the new method, but I haven't done the other objects.


Here's a sample of the Cube.  Heavily commented, so should be easy to see what's going on...


Code: [Select]
function DrawCube(xpos,ypos,zpos)

-- #### DO NOT REMOVE ####
i = numberofvertices
firstvert = i
-- #### DO NOT REMOVE ####



-- ##### VERTICES #####


-- near-side face
-- #0 top left vertex
vertex3dX[i] = xpos - 50
vertex3dY[i] = ypos - 50
vertex3dZ[i] = zpos - 50
i = i + 1

-- #1 top right vertex
vertex3dX[i] = xpos + 50
vertex3dY[i] = ypos - 50
vertex3dZ[i] = zpos - 50
i = i + 1

-- #2 bottom right vertex
vertex3dX[i] = xpos + 50
vertex3dY[i] = ypos + 50
vertex3dZ[i] = zpos - 50
i = i + 1

-- #3 bottom left vertex
vertex3dX[i] = xpos - 50
vertex3dY[i] = ypos + 50
vertex3dZ[i] = zpos - 50
i = i + 1

-- #4 far-side face
-- top left vertex
vertex3dX[i] = xpos - 50
vertex3dY[i] = ypos - 50
vertex3dZ[i] = zpos + 50
i = i + 1

-- #5 top right vertex
vertex3dX[i] = xpos + 50
vertex3dY[i] = ypos - 50
vertex3dZ[i] = zpos + 50
i = i + 1

-- #6 bottom right vertex
vertex3dX[i] = xpos + 50
vertex3dY[i] = ypos + 50
vertex3dZ[i] = zpos + 50
i = i + 1

-- #7 bottom left vertex
vertex3dX[i] = xpos - 50
vertex3dY[i] = xpos + 50
vertex3dZ[i] = xpos + 50
i = i + 1




-- #### DO NOT REMOVE ####
numberofvertices = i - 1
i = numberofedges
firstedge = i
-- #### DO NOT REMOVE ####






-- ##### EDGES #####


-- edgefrom[i] = ID of the vertice the edge should be drawn FROM
-- edgeto[i] = ID of the vertice the edge should be drawn TO
-- "i" is the ID of the edge.

-- near-side edges
-- #0 from near top left to near top right
edgefrom[i] = firstvert + 0
edgeto[i] = firstvert + 1
i = i + 1

-- #1 from near top right to near bottom right

edgeto[i] = firstvert + 2
i = i + 1

-- #2 from near bottom right to near bottom left

edgeto[i] = firstvert + 3
i = i + 1

-- #3 from near bottom left to near top top
edgefrom[i] = firstvert + 3
edgeto[i] = firstvert + 0
i = i + 1

-- far side edges

-- #4 from far top left to far top right
edgefrom[i] = firstvert + 4
edgeto[i] = firstvert + 5
i = i + 1

-- #5 from far top right to far bottom right
edgefrom[i] = firstvert + 5
edgeto[i] = firstvert + 6
i = i + 1

-- #6 from far bottom right to far bottom left
edgefrom[i] = firstvert + 6
edgeto[i] = firstvert + 7
i = i + 1

-- #7 from far bottom left to far top right
edgefrom[i] = firstvert + 7
edgeto[i] = firstvert + 4
i = i + 1


-- connecting edges

-- #8 from near top left to far top left
edgefrom[i] = firstvert + 0
edgeto[i] = firstvert + 4
i = i + 1

-- #9 from near top right to far top right
edgefrom[i] = firstvert + 1
edgeto[i] = firstvert + 5
i = i + 1

-- #10 from near bottom right to far bottom right

-- #11 from near bottom left to far bottom left
edgefrom[i] = firstvert + 3
